Which sequence is correct for the intermediate colours between yellow and red?

Correct answer: Yellow then yellow-orange then orange then red-orange then red

The governing idea is the ordered progression of neighbouring hues on a traditional colour wheel. Moving from yellow toward red, the sequence passes through yellow-orange, orange and red-orange before reaching red. Therefore option A is correct. Green and blue lie away from this yellow-to-red arc, violet is between red and blue, and cyan and magenta belong to another colour-system vocabulary rather than this traditional sequence.
